Pour about 1 cup of the vanilla filling into the center of the crust. Then pour about 1 cup of the pumpkin filling into the center of the vanilla filling. Alternate the remaining fillings in the same manner; concentric circles will form as they spread. To create a marbled effect, gently swirl a knife or skewer through the fillings.

Step 5

Place the cheesecake in a roasting pan and pour in enough boiling water to come 1/2 inch up the side of the springform pan.

Step 6

Bake the cheesecake until the edges are set but the center still jiggles, about 50 minutes. Turn off the oven. Coat a knife with cooking spray and run it around the edge of the cake. Let stand in the oven, with the door ajar, for 1 hour. Transfer from the water bath to a wire rack; remove foil. Let cool to room temperature, about 2 hours. Refrigerate, uncovered, until chilled.
